Definitions
- the invention relates to a closing device which has a container shoulder, a container head for dispensing the contents of the container, and a closure cap, wherein the closure cap is operated with a twisting motion.
- a closure mechanism of this type which is also referred to as fractal closure mechanism, may be used with containers of arbitrary size and design which can be closed with a cap, wherein the container has an integrated container head with an opening for withdrawing measured quantities from the container.
- EP-A-0 554 239 A2 describes a closure mechanism of this type. In this mechanism, a central lid portion presses against the freshness seal affixed to the applicator.
- GB 2 218 077 A proposes to form major portions of the closure mechanism or even the entire closure mechanism as a transparent unit.
- the protective device i.e., the freshness seal
- the cover plate of the closure cap has openings or windows located in the region of the inner cylinder of the closure cap, and a closure lid supported by ribs.
- the closure lid is arranged concentrically inside the cover plate in the form of a closing and sealing surface, with the diameter of the closure lid corresponding at least to the diameter of the container opening, so that the closure lid reliably seals the applicator opening when the closure cap is screwed on.
- Portions of the freshness seal which is centered on the front face of the applicator cone of the container head, can be viewed from the outside through the aforedescribed window in the closure lid, even if the container is closed.
- the diameter of the freshness seal corresponds to approximately to the diameter of the base area of the applicator cone.
- the freshness seal and the cover plate of the closure cap in the manner described above according to the invention, the user can be assured that the freshness seal is intact and that the packaging of the product has not been tampered with before the first use.
- An annular ring or a similar element may be provided on the inside of the closure lid facing the applicator opening of the container head to improve the closing performance of the closure device, wherein the outside diameter of the annular ring is greater than or approximately the same as the inside diameter of the container opening.
- the form and the number of the windows of the closing device may be arbitrarily selected. More openings than necessary for viewing the freshness seal from the outside may be provided, thereby saving material and/or providing a more advantageous design.
- the closure mechanism When used for the first time, the closure mechanism is removed by a rotation of no more than 90°, so that the freshness seal can be pulled off.
- the pitch and the material strength of the threaded portion and the clamping action of the container shoulder provide a reliable seat of the closure mechanism.
- FIGS. 1A and 1B are side cross sectional views of a closure unit
- FIG. 2 is a top view of the closure unit with windows required to make the freshness seal visible form the outside, and
- FIG. 3 is a top view of the closure unit with a large number of openings in the cover plate of the closure cap.
- FIG. 1 A and FIG. 1B elements of the closure unit, in particular a container head with a cylindrical base region 2 followed by an applicator cone 3 , as well as a container shoulder 4 and a closure cap 5 are shown from different viewing angles.
- the an annular ring 15 is provided on the inside of the closure lid 10 facing the opening 11 of the container head to improve the closing performance of the closure cap.
- the container head 2 , 3 and the closure cap 5 may be made of plastic, for example polyethylene.
- Two threaded segments 1 which are implemented as simple helical threads, are arranged in the cylindrical base region 2 of the container head.
- the closure cap 5 which includes an inner cylinder 6 , an outer cylinder 13 and a cover plate 7 , are screwed onto the container head.
- the threaded segments 1 of FIG. 1A engage with a corresponding thread in the end region of the inner cylinder 6 of the closure cap 5 .
- the windows 8 , 12 disposed in the cover plate 7 of the closure cap 5 are shown in the top views of the closure unit of FIGS. 2 and 3.
- the cover plate 7 has only windows 8 which provide a view of the freshness seal 14 from the outside.
- the windows 8 are disposed in the region bounded by the diameter of the inner cylinder 6 of the closure cap 5 , surrounding the closure lid 10 which is connected to the remaining portion of the cover plate 7 through ribs 9 .
- the diameter of the closure lid 10 is selected so as to provide a closing and sealing surface covering the applicator opening 11 .
- An annular ring 15 on the inside of the closure lid 10 facing the opening 11 has an outside diameter approximately equal to the inside diameter of the opening 11 .
- the freshness seal 14 is attached to the font face of the applicator cone 3 , sealing the applicator opening 11 .
- the closure cap 5 has additional openings, windows 12 , in the cover plate of the closure cap 5 .
- the windows 12 are disposed in an annular zone of the cover plate 7 located between the inner cylinder 6 and the outer cylinder 13 , thereby making the shoulder 4 of the container visible from the outside.
- the ribs 9 connect the closure lid 10 in the radial direction first with the inner cylinder 6 and then also with the outer cylinder 13 of the closure cap 5 .
